Shareholders of Ardent Leisure have overwhelmingly backed a proposal to sell the struggling theme park operator’s US entertainment business, Main Event, to NASDAQ-listed restaurant and entertainment business Dave & Busters for $1.1 billion.

The vote means Ardent Leisure will exit the US entertainment market to focus on its remaining Australian businesses: Gold Coast theme parks Dreamworld and WhiteWater World and the SkyPoint Observation Deck at the top of the Q1 skyscraper at Surfers Paradise.
